212723 ÷ 30 
Our goal is to divide 212723 by 30.

Step 1:
The number 30 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 30

On to step 2:
The number 30 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 30

Advancing to step 3:
The number 30 fits into 212 7 times, leaving a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 210 from 212 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 30

Moving on to step 4:
The number 30 fits into 27 0 times, leaving a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Subtract 0 from 27 to get 27.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 30

Going ahead to step 5:
When dividing 272 by 30, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 709.0
The remainder is 2 after subtracting 270 from 272.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 30

Let's proceed to step 6:
The number 30 fits into 23 0 times, leaving a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 7090.0
Deduct 0 from 23 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
When dividing 230 by 30, we get 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 7090.7
If we subtract 210 from 230, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
200 divided by 30 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 7090.76
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
30 goes into 200 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 7090.766
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 7090.766 and a remainder of 0.002.
